To determine which expressions are equivalent to the given expression
, we need to simplify each of the provided expressions and compare them.1. **Given Expression:**
2. **Expression 1:** \(3(2 - 0.6x - 1.2)\) - Simplify inside the parentheses:
- Distribute the 3:
3. **Expression 2:** \(0.9(x - x)\) - Simplify inside the parentheses:
- Multiply by 0.9:
4. **Expression 3:**
5. **Expression 4:**
Now, compare each simplified expression with the given expression
:- Expression 1 simplifies to
, which is equivalent to the given expression.- Expression 2 simplifies to
, which is not equivalent.- Expression 3 is
, which is not equivalent.- Expression 4 is
, which is not equivalent.Therefore, the expression that is equivalent to the given expression is:- \(3(2 - 0.6x - 1.2)\)
